N Nitrit srafifiis PATENT onirica.

Be it vknown that l, lJOHN A. S'rnwAIn), a citizen of the United States, residing at Rutland, county' of Rutland, and State of Vermont, have `invented certain new and useful Improvements in Carbureters, of which the following is al specification, reference being had therein tothe accompanying drawing.

This invention relates to al carbureter, and particularly to a construction 'adapted for application to the inlet port of a gas or In the drawing z-Figure l is a vertical` section through the carbureter, and Fig; 2 is a, horizontalsection throughthe upper portion thereof.

Like numerals. referto like parts in the several views of the drawing. y

This invention comprises an improvement upon the' construction shown in my patent dated March 2,1909 #913,857 and seeks to form a simple and compact construction whereiirtlie arbureting chamber is disposed \\'ithin tho liquid receptacle and is thus adapted for direct connection with a' gas or explosive engine.

Inftlie forni shown the receptacle l0 may be of anydesired size or configuration and' is closedair tight''except for the connection ill from which the gas is discharged and which is preferably connected to the suction port of a `gas engine. At. the lower portion of this receptacle a vaporizing*chamber l2 is disposed and is filled with an absorbent material 18. i which the gasolene or liquid is fed throuigh .the openings 'hlat the opposite ends of the-chamber. This chamber is also supplied with an airv inlet pipe 15 which discharges at the lower portion there-v Speccation of Letters Patent. Application filed Marche, 1909. seriai No. 482,306.

ward therefrom above the liquid level..

within the receptacle 10. This receptacle may be filled with gasolene or other liquid through any preferred opening, for instance, als shown at 18. i

The engine connection 11 from the upper portion of the gasolene tank may be of any` desired character, but is preferably pio vided with a check valve Q0 which also communicates with the cylinder feed pipe for `an engine cylinder. n This pipe may also have within this chamber adjacent thelower porrevcnts the chamber becoming` tion thereof filled `with liquid. As soon as the liquid rises above the lower open ends of these pipes they are sealed thereby and the compression of the vapor in the upper portion of the chamber prevents furthei entrance of liquid therein. A series of the discharge pipes may be used and the operation of the carburetor is automatic both in the carbureting action and its feed to an engine or other object to which the fuel is to be supplied.

Aln the operation of the invention it will be seen that the suction in the piston stroke of the engine is exerted through the feed pipe from the receptacle and draws a supply of gas from the vaporif/.ing chamber through the discharge pipe therefrom. This 'action causes an intake of air at the opposite en'd of the vaporizing chamber and also 'an inward flow of liquidso as to always Having described my invention and setv forth its merits, what l claim and desire to secure by Letters Patent is yvided with openings at' its lower portion` 1. A carbureter comprising a closed receptacle having its lower portion filled with liquid, a vaporizing chamber disposed within said receptacle and sealed at its upper portion and provided with openings at its lower ortion communicating with said receptacle below the liquid level therein, an air inlet extended to the lower portion of said chamber below said level, and a discharge from the lower portion of said chamber extended below said liquid level.

2. A carbureter comprising a closed receptacle having its lower portion illed with liquid and its upper' portion forming a gas chamber, a feed connection with said receptacle above the liquid level thereof, a vaporizingchamber disposed within said'receptacle and sealed at its upper portion and pro- 'communicating' with said receptacle below the liquid level thereof, an air inlet extended to the lower portion 'of said vaporizing chamber below said level, and a discharge from the lower portion of said chamber below said level and communicatin with the gas chamber above the liquid ol said recepta'c'le. y 3. A-carbureter comprising a closed receptacle having its lower portion filled with liquid, a vaporizing chamber therein sealed at its upper portion and provided with filling openings atits lower portion communicating with said receptacle below the liquid level therein an air inlet disposed' at one end of said c amber and extending upward from below said level and outwardly from said receptacle, and a discharge from the opposite 'end of said chamber extending from below the liquid level to a point above the liquid level in said receptacle. 4. A carbureter comprising a closed receptacle having its lower portion filled with liquid, a 'vaporizing chamber therein sealed at its upper portion and provided with iillino' openings at its lower portion communicaing withsaid receptacle below the liquid level therein, an air inlet disposed at one end ofsaid4 chamber and extending upward from below said level and outwardly from said receptacle, a discharge from the opposite end of said chamber extending from below the liquid level to a point above the liquid level in said receptacle, |and means provide ilr said air inlet to permit expansion of the gas -liquid. and its upper portion forming a gas` chamber, discharge connection from said gas chamber, a vaporizing chamber disposed within said receptacle and sealedat its upper portion and provided with an inlet opening at its lower portion below the liquid level oli the receptacle, an air inlet to lthe lower portion of said vaporizing chamber below the' liquid level of the receptacle, and a discharge pipe from said vaporizing chamber extended below said level and communicating with said gas chamber.
